Small-scale Technology Certificates (STCs) and the Small-scale Renewable Energy Scheme (SRES)

The SRES creates a financial incentive for households, small businesses and community groups to install eligible small-scale renewable energy systems such as solar water heaters, heat pumps, solar photovoltaic (PV) systems, small-scale wind systems, or small-scale hydro systems. It does this by legislating demand for Small-scale Technology Certificates (STCs). STCs are then generated at the time of installation, covering the expected amount of electricity generation (output) until the scheme ends in 2030.

The Small-Scale Renewable Energy Scheme (SRES) covers renewable energy innovations like solar water heaters (SWHs) and small generation units (SGUs), for example, photovoltaic (PV) panels, wind and hydro systems (less than 100kWs).

  • STC’s can be claimed as an upfront rebate for SOLAR PV installations.
  • You receive one STC for each MWh generated over a 15-year period.
  • STC’s can be sold as a tradeable commodity through the clearing house operated by the clean energy regulator, or assigned as a point of sale discount if you elect to sign over the certificates to a solar provider.
  • Most companies elect to assign them to the installer or solar provider

STCs and LGCs are managed by the REC Registry. The REC Registry is an online system that:

  • facilitates the creation, registration, transfer and surrender of large-scale generation certificates (LGCs) and small-scale technology certificates (STCs)
  • tracks the ownership and status of all certificates
  • provides access to the STC clearing house, and
  • maintains various public registers as required by the Renewable Energy (Electricity) Act 2000 (the REE Act).

All certificates must be created in the REC Registry before they can be bought, sold traded or surrendered.
